Mobile only (<=639px / coarse pointers); desktop keeps its behaviour.
System integration
- Manifest: id, display_override, monochrome icon, Make my homework
shortcut and a share target (text/URL via GET, files via POST).
iOS startup images for the common iPhone sizes. Pinch-zoom is allowed
again (double-tap zoom is disabled via touch-action instead).
- Share target: /share chooser with New deck / Make my homework; POSTed
files wait in a 10-minute in-memory store, reach the wizard through
sessionStorage and never touch disk.
- Web Share: Share rows for decks (JSON file where supported) and the
homework result, with a clipboard fallback and a toast.
- Offline: a quiet pill appears and Freeze / mode cards are disabled
with a clear reason; input is never lost (error cards keep Retry).
- State: wizard drafts (text, options, photos up to a size budget)
survive reloads and OS kills and are cleared on success; re-tapping
the active tab scrolls to the top; the deck page shows a skeleton
instead of a spinner.
Navigation and gestures
- System Back closes the topmost layer first: a small history-entry
stack (lib/use-back-close.ts) covers the drawer, Settings sheet,
install sheet, deck actions panel and one wizard step; navigations
are never rewound and stale entries are skipped.
- Destructive-but-reversible actions use Undo toasts: deleting a deck
(no confirm) and removing a file in the wizard. Irreversible ones
keep their confirm.
Input and feedback
- Every phone input got inputmode / enterkeyhint / autocomplete /
autocapitalize / spellcheck; Enter on the last field advances the
wizard; a clipboard-paste button appears where the API exists.
- Haptics behind a Settings toggle (on by default): tab switches,
toggles, correct/wrong, completion; Vibration API + the iOS hidden
switch tick, throttled and silent everywhere else.
- Wake lock during the study feed and homework guide, released on
leave and re-acquired when the tab returns.
Verified: new native suite 35/35 (manifest/head/viewport, offline,
share target GET + POST, back-gesture layers, undo, share fallback,
tab re-tap, haptics persistence, draft restore), regression 74/74,
mobile 52/52, wizard 80/80, declutter 116/116, animation 8/8,
i18n 25/25. Lint + build clean. SW freezmo-v23.
Needs a real device (documented in the README): iOS haptic tick,
system share sheet entry, wake-lock grant, iPhone startup images,
iOS edge-swipe back, install prompts. Pull-to-refresh and the app
badge were skipped on purpose.
English stays the default; Czech is a full translation. Only the app chrome
is translated - notes and generated decks keep their own language, which is a
core feature, not a setting.
i18n
- lib/i18n-dict.ts: flat en/cs dictionaries (441 keys each), translate() and
translatePlural() with real Czech plural rules (1 sada / 2-4 sady / 5+ sad).
English is the default and the fallback for a missing key.
- lib/i18n.ts: browser store (freezmo.locale.v1), useI18n() hook, and the
x-freezmo-locale header. The hook's t/plural are bound to the locale React
is rendering with, so the first client render matches the server HTML and
then re-renders in the stored language; module-level t is only for event
handlers and non-React helpers.
- <html lang> follows the choice (inline script + setLocale).
UI
- Settings -> Language segmented control (English / Cestina), plus an EN/CS
button on the key gate for first run.
- Every screen translated: sidebar, header, tab bar, library, deck cards,
folder bar, create flow, all seven activities, study chrome, results,
settings + health panel, API-key gate and help, install sheet, offline and
the deck-not-found page.
- Plural-aware counts everywhere (decks, folders, activities, runs, photos,
documents, pages, words, wrong attempts).
Server
- API routes and guards (generate, grade, health, http-guard, rate-limit,
ollama error mapping) answer in the request's language, so error cards and
the health panel never fall back to English mid-sentence.
Fixes
- A hydration mismatch when a non-default locale was stored silently dropped
the .dark class after hydration; render-time t() is now bound to the
hook's locale (UploadScreen.describeExtraction, ResultsScreen.answerFor,
DeckCard's folder fallback).
- Bumped the service worker cache to freezmo-v4 for this deploy.
Tests: i18n 27/27 (gate toggle, persistence, html lang, Czech plurals,
settings switch) and a rebuilt regression suite 72/72 (English default,
library, create, all 7 activity types, results, settings, install sheet,
offline, PWA, security, Czech smoke).
Rebuilds the look around the spec: an ice scene, one shared glass
recipe, icy accents and glass on every large surface. Visual only —
layout, behaviour, copy and functionality are untouched.
Background
- .ice-scene: fixed, z-index -1, pointer-events none. Navy base
(#070b16 to #0c1426) in dark, pale (#f4f9ff to #e6f1fb) in light,
four drifting glacier blobs (#38bdf8/#60a5fa/#818cf8, 30-60s
transform-only loops), five glossy ice orbs (40-220px radial
gradients with a highlight at 30% 25% and a blue shadow) placed so the
glass blurs them, and an SVG feTurbulence grain at 4-5%.
- prefers-reduced-motion stops the drift; phones get two blobs and two
orbs fewer.
Glass
- One shared recipe (.glass-panel, .card, .sidebar-surface,
.study-chrome, .tabbar, .glass, .gate-card): rgba(255,255,255,.06)
dark / .55 light, blur(24px) saturate(140%) (16px on phones), a bright
1px rim, an inset top highlight and a blue-tinted outer shadow.
- Nested glass (chips, inputs, secondary buttons) is more opaque and
never adds a second blur layer. @supports fallback for no
backdrop-filter. Radii: 24-28px cards/sheets, 14px inputs/buttons,
pills for chips. Cards hover brighter + cyan rim + 2px lift, 180ms.
Colour and type
- Accent is glacier cyan (#38bdf8) to ice blue (#0ea5e9); progress bars
and selected states use the gradient; the active sidebar item is a
frosted highlight with a cyan rim.
- Primary CTA: icy gradient — white to #bfe3ff with ink text in dark,
deep blue in light (biased so the label sits on the darker half and
keeps 5.6:1).
- Leftover slate/black greys replaced with navy-tinted frost tokens.
- Headings are semibold with tighter tracking.
Screens
- Dashboard: the sidebar is one tall inset rounded glass panel; deck
cards are glass.
- Gate: one centred glass card over the scene, orbs visible behind it.
- Sheets/modals: glass over the dimmed, lightly blurred backdrop.
- Study view: question card more opaque (.glass-solid); top bar and
pager are slim glass pills.
Perf: measured on a phone viewport with 4x CPU throttling. The animated
blobs' filter: blur() was the whole cost (150ms vs 33ms per frame), so
they are soft radial gradients with no filter now; idle 60fps, ~17ms
median while scrolling.
Tests updated for the new tokens: contrast 18/18 AA, deck chrome 15/15,
key gate 49/49, install sheet 64/64, deck fixes 15/15, retry 14/14,
zoom 6/6, final ux 12/12, security 8/8, pwa 16/16.
Source artwork committed as assets/app-icon-source.jpeg (1024x1024 navy
rounded square) and scripts/make-icons.mjs rewritten to render every icon
from it with headless Chromium:
- The master is masked at full resolution first (a rounded rect 4px inside
the artwork's own radius), so the JPEG's anti-aliased white edge never
survives and small sizes downscale with clean alpha.
- PWA icons (192/512) and favicon-32 keep the rounded square with
transparent corners; apple-touch 180/167/152 are full-bleed (iOS paints
transparency black) with the artwork zoomed 20% to crop its corners;
maskable-512 keeps the artwork inside the 80% safe circle on a matching
navy field.
- iOS splash screens regenerated with the new mark.
- app/favicon.ico regenerated (PNG payload in an ICO container); the old
app/icon.svg removed so the browser tab can't fall back to it.
- Install sheet's app card now shows the real icon, so the home-screen
icon is recognisable.
- Service worker CACHE_VERSION bumped to freezmo-v3 so installed clients
pick up the new assets.
- README updated (source artwork + script description).
Verified: pwa 16/16, install sheet 64/64, final ux 12/12, key gate 49/49,
zoom 6/6; every icon route serves 200 and the manifest/head reference the
new files.
Steps
- iOS now uses the exact flow: Safari users get 4 steps (⋯ → Share/More →
Add to Home Screen → Add); non-Safari (CriOS/FxiOS/EdgiOS/in-app) get a
first 'Open this page in Safari' step and 5 total. The vague 'in some
browsers it's under…' wording is gone.
Chips and icons
- The ⋯ chip renders a single three-dot icon (icon-only pill) instead of
the icon plus an '⋯' character (which showed two sets of dots).
- The More chip uses a chevron-down icon instead of the rounded-square.
- The accent pill uses real iOS blue: #0A84FF dark / #007AFF light, still
the only coloured element.
- Steps and chips share one 16px type scale; chip labels are medium weight.
Typography and layout
- Numbers are small muted circles in a fixed 24px column, aligned with the
first text line via matching line-height.
- Removed trailing periods after chips; steps tightened.
- Bottom padding is calc(24px + env(safe-area-inset-bottom)) and a
secondary 'Maybe later' button sits below the steps.
- max-height 90dvh with inner scrolling; 36×4px low-contrast handle with
real swipe-down-to-close (momentum off, spring back).
- App card shows the hostname only (no port), truncated.
Themes
- Dark (default): layered surfaces #1c1c1e sheet / #2c2c2e card / #3a3a3c
chips with 8% white borders; subtle logo tile instead of solid white;
backdrop is 50% black with 4px blur.
- Light only when the app theme was explicitly set to light, ignoring the
system preference; borders #e0e0e0, chip fills #f2f2f2.
Also fixes a crash the test pressure exposed: a 429 (rate-limited)
/api/health response crashed Settings at health.vision.available.
fetchHealth now rejects non-OK/malformed responses so the dialog shows its
error banner instead of the app error screen.
Install-sheet suite now 64 checks; pwa/final-ux/security/contrast green.
- New InstallSheet mounted in the root layout: appears ~1s after load on
iOS/Android phones and tablets, over any screen including the key gate,
with a dimmed backdrop. Never on desktop, never in standalone mode, and
at most once per 7 days after a dismissal (localStorage).
- Platform/browser detection (lib/install.ts): iPhone/iPad incl. iPadOS
reporting as Mac with touch, Android, Safari vs Chrome vs other vs
in-app browsers, with step 1 adapted accordingly.
- iOS: numbered steps with chips (Safari, Share, ... , More, Add to Home
Screen) and the accent Add pill. Android: captured beforeinstallprompt
turns into a native Install button; fallback steps use Install app /
Add to Home screen chips and an accent Install pill.
- Close via X, backdrop, Escape or swipe-down on the handle; the site is
untouched afterwards. Anchored to 100dvh so browser toolbars never hide
the last step; pb-safe respects the home indicator.
- Dark sheet by default; light only when the app theme was explicitly set
to light. Settings gains a mobile-only Install app row that reopens it.
- The inline head script captures beforeinstallprompt before hydration and
records appinstalled. Old InstallHint banner removed.
- Tests: new install-sheet suite (45 checks across iPhone Safari/Chrome/
in-app, Android Chrome/Samsung, desktop, prompt path, dismissal, 7-day
expiry, standalone, Settings row, both themes); pwa suite updated.
